PIRAEUS, Greece (AP) — About 400 asylum-seekers who had been held in the severely overcrowded Moria migrant camp on the Greek island of Lesbos have arrived in Greece’s main port of Piraeus to be transferred to other camps and residences on the mainland.

The asylum-seekers, mainly families from Syria, Afghanistan and African countries, arrived Tuesday onboard an overnight ferry from Lesbos. They are among around 2,000 people whom the government has pledged to move out of Moria, a facility built for 3,100 people but which is at nearly three times capacity.

Charities have slammed conditions in the camp, citing cases of sexual attack, deplorable sanitation and an increase in suicide attempts among residents. The local regional governor has threatened to shut the facility unless the government improves conditions.
